    33  This command verifies that the required charts, as expressed in 'Chart.yaml',
    34  are present in 'charts/' and are at an acceptable version. It will pull down
    35  the latest charts that satisfy the dependencies, and clean up old dependencies.
    36  
    37  On successful update, this will generate a lock file that can be used to
    38  rebuild the dependencies to an exact version.
    39  
    40  Dependencies are not required to be represented in 'Chart.yaml'. For that
    41  reason, an update command will not remove charts unless they are (a) present
    42  in the Chart.yaml file, but (b) at the wrong version.
